Do we really need to spend so much time parsing this out, though?
(As our mods might say, "This post lands at random", and isn't meant to signal you out above and beyond any and everyone else discussing it; I just chose to stick my flag in the mountainside by this comment.)
IMO, the point and goal is to figure out "where Brian might have gone".
Again IMO, "if this man is/was in fact Brian", then it seems extremely unlikely that he would ever mean "California, North Carolina", no matter how askew his worldview was at this point (again, IMO); simply because "California, North Carolina" was never a Brian + Gabby destination.
Thus, if it's an innocent random person, IMO it's possible said random person could mean "California, NC".
If it's in fact shown to be Brian, I consider it next to impossible that he would be gunning for "California NC"; nor, in turn, that he would be perceiving it as having something to do with Gabby.
Again, not trying to dictate the course of the conversation; just pointing out these potential time-wasting tangents early in the game before they derail entire multiple threads.
I mean, someone a few threads ago even wanted me to consider the statistics about the overall likely theft of Ford F-150s; which literally has zero to do with inside baseball, because we're not trying to measure "how often any F-150 driving down the road gets stolen in general"; because our topic is, did BRIAN steal a vehicle, and in particular the single vehicle being referenced by our tipster, KWIM?
